What we measured
The three artifacts a lighting plan is actually drawn from. Every figure below comes off our own spec sheet; where we do not have a measurement, the page says so instead of estimating.
What the DS320S Bar is for
A 320W linear bar in a truss-style aluminium frame with the driver mounted on top, out of the light path. 896 µmol/s with a deep-red-weighted full spectrum — a strong peak near 660nm over a broad white base. Built as a supplemental and inter-row fixture for rooms where the top light is set and you need to add photons in a defined strip.
What you get
- 896 µmol/s, 320W at 277VAC.
- Deep-red-weighted full spectrum: a defined blue peak near 450nm, a broad 500-620nm base and a dominant peak near 660nm.
- 2ft × 4ft flowering, 4ft × 5ft vegetative coverage, 120° beam.
- Truss-frame construction, 36" × 4.33" × 5.04", 4.8kg, with the driver externally mounted for heat separation.
- Two hanging bails for fast positioning between rows or over a gutter.
- 0-100% dimmer knob; 120-277VAC or 277-480VAC input, power factor above 0.95.
- Passive cooling to 40°C ambient, mounting height 6-24 inches.
- Five-year standard warranty, L90 beyond 50,000 hours.

Before you spec it
DS320S or DS320G — they are the same wattage?
Same 320W and same 896 µmol/s, different optics and spectrum shaping. The DS320S is 36 inches long over a 2ft × 4ft flowering strip; the DS320G is 31.9 inches over a narrower 2ft × 3ft strip with its red peak sitting nearer 690nm and a longer far-red tail — shaped for greenhouse supplemental work under natural light.
Where does it sit against the DS400D?
The DS400D is a 400W top light at 1,120 µmol/s over the same 2ft × 4ft footprint. The DS320S is the supplemental sibling — less output, external driver, truss frame, easier to place between rows.
Can I use it as a primary top light?
You can, over a 2ft × 4ft strip. But if a bar is your top light, the DS400D gives you 25% more photons for 25% more power in a similar envelope.
How does it mount between rows?
Two hanging bails at the ends of the truss frame, at 6-24 inches from canopy. The external driver sits above the frame, so it is not radiating into the canopy from directly overhead.
